mmar and arithmetic. It not only
develops his muscles, but enlarges his mental capacity; it not only
fills with excitement the idle hours of the long day, but it sharpens
the judgment, and helps to fit the boy for the active duties of life.

It need not be supposed, because Bobby had to turn his attention to
serious things, that he was not fond of fun; that he could not or did
not play. At a game of round ball, he was a lucky fellow who secured
him upon his side; for the same energy which made him a useful son
rendered him a desirable hand in a difficult game.

When the supper things were all removed, the dishes washed and put
away, Bobby drew out his pocket memorandum book. It was a beautiful
article, and Mrs. Bright was duly astonished at its gilded leaves and
the elegant workmanship. Very likely her first impulse was to reprove
her son for such a piece of reckless extravagance; but this matter was
set right by Bobby's informing her how it came into his possession.

"Here is my ledger, mother," he said, handing her the book.

Mrs. Bright put on her spectacles, and after bestowing a careful

"Fifty books!" she exclaimed, as she read the first entry.

"Yes, mother; and I sold them all."

I went away."

"You didn't borrow it of me."

"But I shall pay it."

Mrs. Bright was astonished at this unexpected and gratifying
result. If she had discovered a gold mine in the cellar of the little
black house, it could not have afforded her so much satisfaction; for
this money was the reward of her son's talent and energy. Her own
earnings scarcely ever amounted to more than three or four dollars a
week, and Bobby, a boy of thirteen, had come home with fifteen for
five days' work. She could scarcely believe the evidence of her own
senses, and she ceased to wonder that he talked big.

It was nearly ten o'clock when the widow and her son went to bed, so
deeply were they interested in discussi
